Example 4
The week schedule for the building is set with comfort periods all
weekdays: 06.00 - 20.00. Sometimes, the desired flow temperature
must be constant on 65 °C.
An override relay is installed and the flow temperature must be
65 °C as long as the override relay is activated.
Choose an unused input, for example S8. Connect the contacts of
the override relay.
Settings in ECL:
1. Select circuit > MENU > Settings > Application > Ext. input:
Select the input S8 (the wiring example)
2. Select circuit > MENU > Settings > Application > Ext. mode:
Select CONST. T
3. Select circuit > MENU > Settings > Flow temperature >
Desired T (ID 1x004):
Set to 65 °C
4. Remember to set the circuit in question in scheduled mode
("clock").
Result: When the override relay is activated, the ECL 210 / 296 / 310
will operate in Const. temp. mode and control a flow temperature
of 65 °C.
When the override relay is not activated, the ECL 210 / 296 / 310
will operate according to the schedule.
